Details

In the Linux kernel, the following vulnerability has been resolved:

net/rds: Clear reconnect pending bit

When canceling the reconnect worker, care must be taken to reset the reconnect-pending bit. If the reconnect worker has not yet been scheduled before it is canceled, the reconnect-pending bit will stay on forever.

Severity

7.5 (High)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
